Effects of Black Ginseng Water Extract under the Inflammatory Conditions of Cultured Sebocytes and Outer Root Sheath Cells.

ABSTRACT:

Background

Ginseng has been used in Korea for a long time as a restorative herbal medicine. Black ginseng (BG) is made from red or white ginseng by multiple steamy and dry processes. Although BG has been reported to have anti-inflammatory potential, studies on its influence on inflammatory skin disorders are lacking.

Objective

To investigate the effects of BG under the inflammatory conditions of cultured sebocytes and outer root sheath (ORS) cells.

Methods

The cultured cells were treated with 0.1% dimethyl sulfoxide, 5 µg/ml lipopolysaccharide (LPS) or 5 µg/ml LPS+50 µg/ml BG for 6 hours and 24 hours. Reverse transcription-polymerase chain reaction (RT-PCR), real-time PCR, enzyme-linked immunosorbent assay, western blotting, immunofluorescence staining and Nile red staining were performed for analysis of inflammatory biomarkers and sebum-related biomarkers.

Results

BG brought out the increased gene and protein expression of inflammatory biomarkers such as interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor-α, in the LPS-treated sebocytes and ORS cells. In addition, BG induced increased expression of TLR4, p-c-jun, p-JNK and p-iκB in LPS-treated sebocytes and ORS cells. Furthermore, it significantly increased the expression of LL-37 and the production of sebum in LPS-treated sebocytes.

Conclusion

It may be possible for BG to increase the expression of inflammatory biomarkers in inflammatory skin disorders, such as acne.

Project description:The excessive release of reactive oxygen species (ROS) can result in the development of chronic inflammation. The mechanisms involved in inflammation are various, with endoplasmic reticulum (ER) stress known to be among them. We have previously shown that black ginseng (BG) reduced lipid accumulation in and enhanced the antioxidant function of the liver in vitro and in vivo mostly due to ginsenoside Rb1, Rg3 and Rk1 components. Therefore, this study investigated the antioxidant effect of BG on the intestines and its possible mechanistic pathway through ER stress. The results showed that BG extract decreased ROS and nitric oxide (NO) production and reduced inducible nitric oxide synthase (iNOS) expression levels in vitro, and these results were confirmed by zebrafish embryos in vivo. However, this phenotype was abolished in the absence of inositol-requiring enzyme 1 (IRE1α) but not in the absence of protein kinase RNA (PKR)-like ER-resistant kinase (PERK) or X-box-binding protein 1 (XBP1) in the mouse embryo fibroblast (MEF) knockout (KO) cells, suggesting that BG elicits an antioxidant effect in an IRE1α-dependent manner. Antioxidant and anti-inflammatory effects were assessed in the liver and intestines of the mouse model affected by nonalcoholic fatty liver disease (NAFLD), which was induced by a high-fat/high-fructose diet. In the liver, BG treatment rescued NAFLD-induced glutathione (GSH), catalase (CAT), tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 expression. In the intestines, BG also rescued NAFLD-induced shortened villi, inflammatory immune cell infiltration, upregulated IL-6, cytosine-cytosine-adenosine-adenosine-thymidine (CCAAT)/enhancer-binding homologous protein (CHOP) and binding immunoglobulin protein (BiP) expression. In conclusion, our results show that BG reduces ROS and NO production followed by inflammation in an IRE1α-dependent and XBP1-independent manner. The results suggest that BG provides antioxidant and anti-inflammatory effects through an ER stress mechanism.
